Um I have been running a GMB new brand pump for over a year now.. probly about 1 1/2 years now maybe more actually and i havent had a single issue with it... It was leaking out of the weep hole for a few months very very slowely but it stopped. Personally i dont think there is anything wrong with getting the GMB New pump.. It has good reviews.. mine has lasted almost 2 years.. And its cheap and it has a lifetime warranty as well i believe.. Just give advance auto parts your phone number anytime you buy something big from them so if you lose your reciept you can still return it via phone number..

I used a Felpro gasket but i also used The right stuff rtv in the spray can (same stuff i used for my intake manifold) and put a small bead on both sides of my gasket.. I had an issue by just using the felpro gasket alone to where one corner started leaking probly from the timing cover being uneven after using a air tool to clean the gasket off

Ok that's what it was. The welded plates are the up dated version, the old ones used to just have rivets.

Glad to hear it! Hopefully mine will hold up a long time then as mine has the welded plate as well.

I will be trying a hesco next if the new mopar craps out. When I do though the tstat housing will get relief cut or just buy a powder coated one thats high volume. Just gotta see if the mopar lower hose still comes with a spring so it doesn't close up with pump suction. I really am starting to wonder if stray voltages are part of the culprit in all these water pumps. Is the seal in them spring loaded or a ceramic type seal? I read an extensive article on the electrolysis factor in engines, but I can't find it again. Are you guys noticing any pitting or anything like that? Keeping water in a jeep seems to be a challenge.

Or it could be castings are getting reproduced and copied to the point the tolerances are crap.

That seemed to be the case with my Mopar pumps.

I doubt electrolysis could work so quickly on a seal spring but guessing.

I've seen napa pumps with outright casting flaws. That was the one before the mopar one now. On the napa pump the seal didn't leak but the bearing was so wobbly I don't see how it didn't. The advance pump before that one was the same way. Lol, are we going to have to run electric pumps on an adapter plate?
